IMPROVEMENT IN CARS FOR TRANSPORTING COAL.

Specification forming part of Letters Patent No. 152,630, dated June 30,1874; application filed November 28, 1873.

To all whom 'it may concern:

`Be it known that I, JOEL HAINES, of West Middleburg, in the county ofLoga-n, Ohio, have invented an Improvement in Coal-Cars for Railways,ofwhich the following is a specilication:

This invention relates to means for loading, transporting, and unloadingcoal.

The irst part of the invention consists in a detachable truck or framefor application to a common flat railway-car, or gondola, and providedwith sloping-sided dumping-boxes, which are lled in the mine, thenloaded on the car, and, on reaching their destination, are lifted oft'and readily dumped to discharge the load.

The second part of the invention consists 'in a traveling derrickapplied to the car, or

to a train of cars, for'lit't-ing the boxes to and from their seats.

The third part ot' the invention consists in a peculiar grapple, bymeans ot' which to susmay be the platform or deck-frame of an ordinaryhat car, or gondola, which may, if preferred, be untloored, as in theillustration. A truck, B,is applied to the deck A by means of standardsz, attached to the truck, and entering the ordinary sockets y. Thistruck is a rectangular frame, with vertical sides and ends, of which theformer areconstructed with sloping-sided notches w, which form seats forboxes C, having' bottoms of corresponding shape. These 'boxes are equalin length to the width of the car, and in width and height they are ofvariable dimensions. Their sides are parallel, inorder that they mayload closely together. Their ends are likewise parallel, and arestrengthened and enlarged by means of plates fw. These may serve toprevent vthedisplacement of the boxes, but cleats o are preferablyapplied to the bottoms ofthe boxes for this purpose. The end plates ware constructed with pivot-sockets l, by which to suspend the boxes, andarranged below the center of gravity, so as to facilitate dumping; alsowith sockets 2 at one end, to receive a locking-pin. A derrick, D, and agrapple, E, applied thereto, constitute the means for handling theboxes. ln the illustration a traveling derrick is employed, dovetailedways u being formed in or attached to the edges of the platform A forits reception. The carriage t of the derrick consists of a strong frame,which is prevent-ed from spreading by the doveta-iled ways. Aturn-table, s, is pivoted to the top of this carriage so as to swinghorizontally, and on this a fulcrumpost, r, and a windlass, q, ofapproved construction are mounted. In the fulcrum-post a lever, p, ispivoted at, say, one-third of the distance between its outer end,whereit carries the grapple E, and its rear end, where it is connected to thedrum of the windlass q by a rope or chain, o. The windlass is preferablyfurnished with power-multiplying gear 3; but, owing to the employment ofthe liftinglever p, a single spur-wheel and pinion will be suflicient. Aretaining-pawl, 4, Fig. 2, is also applied to the windlass. A forkedstandard, n, which may constitute a part ot' the windlass, receives therear end of the liftinglever when a box is elevated, and supports thesame laterally. The weight of the box is sustained by the holding-pawlel, and the box is swungoft' to either side of the car by means of theturn-table. The grapple E, for suspending and dumping the boxes, isattached to the lifting-lever by means ot' a shackle, on, so as toswivel, to some extent, at least. The grapple is composed of a pair ofjaws, Z, a fulcrumstrut, k, and suspension-links i, uniting the jaws,and a latch, h, hinged to one of the jaws l, to engage with thelocking-sockets 2, to prevent the premature dumping of the boxes. Eachof the jaws carries a suspending-pivot,

to engage with the pivot-sockets l of theA boxes. The parts of thegrapple are so constructed and arranged that the weight of the suspendedbox tends to press the jaws together, and the accidental unshipping of abox is thus precluded. When a box has been swung into proper position itis released by lifting the latch h, and it is then readily dumped byturning it on its pivots l, as illustrated in Fig. 2. rlhe empty box maybe returned toA its seat and detached by loosening the shackle, and thederrick may then be shifted so as to bring the shackle over another box,as illustrated by dotted lines in Fig. l, and thus each of the boxes maybe removed, dumped, and replaced. When one car has thus been emptied thederrick may be transferred to another, the carriage being adapted tospan the spaces between the cars, and an entire train may thus beunloaded or loaded; or xcd derricks at the loading and unloading pointsmay be employed, in combination with cars otherwise constructedaccording to this invention, as illustrated in Fig. 3. It is designedthat the boxes shall be filled in the mine and then lifted to place. Inreturning to the mine a large number of trucks and boxes may be carriedby a single car, and the cars thus cleared may be used for returnfreight; or the cars may be thus converted at any time. Themultiplication of cars, in providing for carrying and dumping coal, isthus obviated, While most effective and simple means for this purpose isprovided. The number of boxes to be carried by each car will bedetermined by the length and capacity of the flat cars of the differentroads on which the invention is employed.

rlhe following is claimed as new:

l. The detachable truck B and the dumping-boxes C, in combination withan ordinary flat car, A, for carrying' coal, in vthe manner set forth.

2. The traveling' derrick D, composed of a carriage, t, turn-table s,fulcrum-post o", liftinglever p, Windlass q, and rope or chain o, incombination with a car or cars, A, furnished with Ways u, substantiallyas and for the purposes specied.

3. The grapple E, composed of jaws l, fulcrum-strut k, links i, andlatch L, in combination with a derrick, D, and dumping-boxes C,substantially as described, for the purpose specified.
